[AArch64] Backport of PR target/70044 fix to GCC 5

        PR target/70044
        * config/aarch64/aarch64.c
        (aarch64_override_options_after_change): When forcing
        flag_omit_frame_pointer to be true, use a special value that can
        be detected if this function is called again, thus preventing
        flag_omit_leaf_frame_pointer from being forced to be false.

        * gcc.target/aarch64/pr70044.c: New test.
